To aZZ whom it may concern:

Be it known that we, LEWIS CLARKE, a resident of Penarth, and HUBERTCLARKE, a resident of Cardiff, Kingdom of Great Britain andIreland,subjects of the Queen of Great Britain and Ireland, haveinvented certain new and useful Improvements in and Relating to the Tipsand Ferrules of Umbrellas or Walking- Sticks, of which the following isa specification.

Our invention relates to improvements in tips and ferrules for umbrellasor walkingsticks; and it consists in the novel devices hereinafterdescribed and claimed.

According to this invention the tip instead of being a fixture in theferrule is removable and can be withdrawn at will, and another can besubstituted without the removal of the ferrule from the stick.

Our invention will be understood by reference to the accompanyingdrawings, wherein similar parts are indicated by similar lettersthroughout both views.

Figure 1 represents a central vertical section through a ferrule and tipmade in accordance with this invention, and Fig. 2 represents a similarview showing a modified form of tip.

In Fig. 1, a represents a tip consisting of a steel spike, which isprovided with a barbed stem a, around which is molded the plug 1), ofindia-rubber or other compressible and expansible material.

0 represents the ferrule, which is made of any suitable hard materialand corrugated at its lower end in the form of screw-threads.

The plug 1) is inserted into the corrugated portion of the ferrule bybeing compressed and started into the end thereof and then screwed in toits fullest extent, as shown.

After being thus inserted the material of the plug bwill expand, and thesame will be held securely within the corrugations.

The tip a is removed by simply unscrewing.

In Fig. 2 a rounded, tip at and its plug d are shown as substituted forthe spiked tip a, and its corresponding plug b.

Any other form of tip havinga compressible and expansible plug securedthereto, as shown in the drawings, may be used in connection with theferrule shown, and we do not wish to limit ourselves to the two forms oftips herein shown and described.

Having thus described our invention, what we claim, and desire to secureby Letters Patent of the United States, is-

1'. The combination with a ferrule having an open end, of a plugremovablyiuserted in the said open end and a tip having a stem securedin the said plug, substantially as described.

2. The combination with a ferrule having an open end interiorlyscrew-threaded, of a plug removably inserted in the said open end, and atip having a stem secured in .the said plug, substantially as described.

3. The combination with a ferrule having an open end and corrugations inthe said open end of a plug of elastic material removably inserted inthe corrugated end and a tip having a stem secured in the said plug,substantially as described.

In witness whereof we have hereunto set our hands in presence of twowitnesses. LEWIS CLARKE. I-IUBERT CLARKE. Witnesses WM. HULIN, A. T.ROWLAND.
